Hi, if you are talking about picking up sts around the edge of the blanket and knitting a trim, then there is a video here under basic techniques, then look to the right and click on more and scroll down & Amy has a video instructing the method for picking up the sts along the edge after it has been completed. Hope this was helpful...if not, just let us know; someone around here will help you get what you want
I also found another tip here that may also help.
